T0 all whom, it may concern:

Be it known that I, JOHN CLAYTON, a citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have made a certain new and useful Invention in Plows; and I declare the followingto be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

Fig. 15 is a side view of the the same. Fig. 16 is a detail side viewof the rear crank-bearing' on the furrow side of the machine. Fig. 17 is an end view of the same.

The invention relates to wheeled plows; and it consists in the novel construction and combinations of parts as hereinafter set forth.

In the accompanying' drawings the letter a designates the frame, which is supported by the landside-wheel b, the furrow-wheel c, and the rear or caster wheel (Z. The frame is vertically adjustable on the stern c of the furrow-wheel and is adjustable crankwise on the landside-wheel.

The plow-beam f is connected to aforward crank g and to a rear crank h, these cranks having bearings on the frame-bars, the front ends of which are attached to a yoke portion 7c, which opens downward, providing an inframe is adjustable on the stem of the furrowwheel, the loose collar of which is provided with a fulcrum-stud m., to which is pivoted the lever p, said lever being connected to the front or yoke portion of the frame by means of rocker-link e projecting upward. The holding-ratchet 71. for this lever forms a part of the bracket q, which is secured to the frame.

The rear portion and land side of the frame is adjustable by means of the crank-axle r of the landside-wheel, said crank-axle being rigidly secured to a lever s, which is arranged to be held in adjusted position by means of a ratchet t of the frame.

The rear crank /z of the plow-beam is also provided with a rigidly attached lever o, whereby the plow-beam isy adjusted up or down at its rear portion, such adjustment being secured by means of the ratchet w of the frame.

The pole 2 is connected to the top of the stem of the furrow-wheel, said ste-m being provided with an arm 3, to which is attached the frontend of a connecting-rodv 4, the rear end of which is connected to an arm 5 of the stern 6 of the caster-wheel in such wise that in turning the plow these wheels are properly di-l rected in a correlative manner.

7 indicates the furrow-wheel bracket, which is adjustably secured to an outward bend of the frame on the right side of the same and is formed with a Vertical channel 8 in its back portion to receive a brace-rib 9 of the loose collar 10 between the fast collars c e, to which the stem c of the furrow-wheel is secured.`

IOO

which the pole is secured.

1() thereupon forms an extended guide for l to the back support 29, which may form a the bracket of the frame in any position of the adjustment of the latter. It also facilitatesv the adjustment of the frame by the lever of this side, because the extent of the bearing precludes binding'. The bracket is provided with a guide-cap 14, forming a stop, and when the lever is lifted to its full height the bottom of plowshare is depressed below the wheel c l in position for opening first furrows. The teeth of the holding-ratchet of the adjustinglevcr line with the lever in its different positions, so as to secure it firmly in holding the adjustment in any position.

To the top of the furrow-wheel stem is secured a toothed cap-plate 16, having a square bearing for a square seat at the end of said stem, to which this plate is rigidly secured. To the stem is also connected the toothed poleplate 17, which engages the cap-plate 16 and is adjustable circularly thereon. The poleplate 17 is provided with an arm or lug 18, to The adjustment of the plates 16 and 17 is secured by means of a suitable nut. By means of these devices the pole can be adjusted to suit the draft according to the work. The arm or lug 13 is formed with a cylinder edge 19 to receive the pole-coupling plate, which is secured thereto by means of a set-screw. The cap-plate 16 is provided with an arm 3, hereinbefore referred to, for the attachment of the connecting-rod f1, extending to an arm of thc stem of the caster-wheel.

The adjustments of the cap and pole plate are for the purpose of lining up the pole with the neck-yoke of the team.

The axle r of the land-wheel extends from the land side to the furrow side of the frame and is seated in bearings 20 of said frame. By running this axle to the furrow side great strength is secured to the structure on account of the extending bracing provided, the combination being such that in the lowest throw of the levers the plow-beams do not touch the axle. The shoe of the land-lever, whereby it is secured to this axle, is provided with an arm or lug 21, to which the rear end of the equalizing coil-spring 22 is attached, the front end of said spring being connected to a lug 23 of the frame in front by means of a hook and thumb-nut.

The stem 6 of the rear or caster wheel is seated in an adjustable bearing 24 of a bracket 25, which is bolted to the rear of the frame. The bracket is provided with a vertical channel or seat 26 for the longitudinal rib 27 of the stem-bearing, which is pivoted in the seat 26 at its lower end. At the upper end of the seat 26 is provided a set-screw 28, which is used for adjusting the position of the rear wheel. By setting up this screw the stembearing is forced backward, thereby pressing the wheel to the ground. At this part of the frame the seat-spring is attached, being bolted part of the bracket, the whole being secured to the frame by one bolt.

The upper end of the stem of the rear wheel is provided with the arm 5, which carries a spring rod or bolt 30, to which the connecting-rod 4C is attached. The bolt has a movement back and forth in its spring connection as pulled by the rod when the rear wheel is brought to short angles in turning corners, and when the plow is pulled in line by the team the spring assists in throwing the rod into position.

The plow-beam is provided with a front crank-bearing 31, which is secured to the side of the plow-beam and has an opening semicircular at the top, as indicated at 32, to conform to the crank g, on which this bearing rests. This opening is extended downward and is provided with a closing-bolt 11. In this manner the crank is allowed free movement in the bearing. When the bolt 11 is removed, the crank will drop out of the bearing, thereby facilitating the knocking down of the plow. The rear crank-bearing33 is also bolted to the side of the plow-beam and is formed with an angular rounded opening to receive the rear crank 71., this opening being closed at its lower end by means of a bolt. The opening of this rear crank-bearing comprises a 'horizontal upper branch and a vertical descending branch communicating therewith at its end, and the opening is of sufficient extent to allow play of the crank-axle therein up and down and back and forth. By this construction the crank is allowed to drop vertically when the land-wheel drops down into holes ordepressions in the ground or to allow the plow to rise up over obstructions without sharp shocks, thereby reducing the friction on the bottom and conserving the general structure. Also by means of the horizontal portion of the opening the plow-beams are allowed to slide forward upon the action of the cranks when the lifting-lever is operated, which materially facilitates the throw.

The front and rear plow-beam cranks are provided with arms 36, which are connected by a rod 37, consisting of two portions having their proximate ends threaded to engage the turnbuckle connections 38, whereby the rod is rendered adjustable. When the turnbuckle is operated to lengthen the rod, the front crank is depressed, the rear crank being held stationary by its lever connection. This adjustment enables the operator to give more or less dip to the plowshare. The front arm 36 is usually made in hook form for the attachment of the crank-spring 39, this being anchored to the rear part of the frame by means of a threaded rod and thumb-nut.v

The rear crank-bearing of the plow-beam may be made closed at its lower end; lbut the open end and bolt construction is preferred.

Two plow-beams are readily connected in a IOC) IIO

wheel-plow of this character, the right plowbeam being usually shorter than that on the left, as indicated in the.drawings.

By the improvements described itis designed to secure an easy adjustment of the frame and plow-beams and a vertical motion of the pivot-pin, whereby the lever is connected to the stem of the furrow-wheel. Also it is designed to facilitate the action and security of the furrow-wheel lever by making' the distance from the pin'center to the teeth on the ratchet equal in whatever position the lever is placed in said ratchet. The crank-bearings of the plow-beams being' open gap-bearings not only allow for play of the plow-beams and frame, but also facilitate the setting up and knocking down of the plow, in this way providing for the exigencies of shipment. The adjustment of the fontplow-beam crank by means of the connecting-rod provides for raising or lowering the point ends of the plows. When the plow becomes worn or loses its dip or suction, the point can be lowered, so as to give it a sharper inclination to take the ground. The'draft is readily adjusted by the pole-connection devices to suit the neck-yoke of the team and to cause the furrow-wheel to track in a satisfactory manner.

Having described this invention, what I claim, and desire to secure by Letters Patent, is
